I have a cordless drill, over the years the chuck has moved further away from the body of the drill, opening up a large gap. It no longer fits in my toolbox!
Black and Decker KC1282F Cordless Drill
How are these keyless chucks attached? Can I remove and re-attach the chuck so that it sits flush with the body of the drill?
I tried the method in Hightower's answer, which, it is now clear, is the correct procedure.
However the screw appeared to be a Torx screwhead. Here's what happened when I tried to turn it clockwise (by hand, using a normal sized screwdriver) ...
I may have to buy a suitable bit for an impact driver. Or wait for the chuck to fall off whilst I am drilling. Or just buy a new drill.
